I Application filed July 29, 1901. Serial No. 70,160. (No model.)

T0 at whom, it nuty concern-.-

Be it known that I, CLINTON A. TANSLEY, a citizen of the United States, residing at Fort Plain, in the county of Montgomery and State of New York, have invented a new and usef ul Oar-Lock, of which the following is a speciiication. V

This invention relates to oar-locks; and the object of the same is to provide simple and effective means in the construction of an oarlock to afford an oarsman every facility for handling his oar with dexterity and plying in the water in the several evolutions of feathering, carrying, and in shipping, as well as convenience in application in a reliable manner.

The invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

In the drawings, Figure 1 isa side elevation of a portion of a boat, showing the improved oar-lock applied thereto and having a portion of an oar therein in shipped or partiallyshippedposition. Fig. 2 is a perspective View of the improved oar-lock. Fig. 3 is a transverse vertical section of the improved oarlock, showing partsin elevation.

Similarnumerals of reference are employed to indicate corresponding parts in the several views.

The numeral .1 designates an upper table, having a concave recess '2 in the upper side thereof to receive the oar-shank and also provided with diametrically-opposed ears 3, an under recess l, surrounding a depending screw-threaded post 5 at the center, and a pcripheral flange 6. The said upper table is mounted on a lower table 7, having aperipheral shoulder 8 to loosely receive the flange 6 of said upper table and also having an upper recess 9, which will be contiguous to the recess at when the two tables are operatively disposed in relation to each other. Through the center of the table 7 a vertical opening 10 is formed to permit the post 5 to extendbolt being provided with a removable nut 15 for convenience in assemblage and disconnection of the said parts. The thole-pin is square in cross-section and is fitted in a similarlyshaped socket secured to or formed in the rail or other upper portion of the gunwale of the boat to prevent the said thole-pin from turning, though said pin may be inserted in or withdrawn from its socket, as may be desired.

The recesses 4 and 9 form seats or races for steel balls 16, and when the two tables are assembled they are held against disconnection by a nut 17, engaging the lower end of the post 5 between the upper portions of the arms 11. It will be seen that the two tables are free to unitedly swing on the head of the thole-piu and that the upper table is permitted to horizontally rotate on the lower table to accommodate the variety of evolutions or movements of the car in carrying into effect the several operations of feathering, carrying, and shipping, as well as allow the blade of the oar to catch as deep in the water as may be desired by the oarsman. Theoar-shank is held in the concave recess 2 of the table 1 by an arcuate yoke 18, which is applied diametrically across and above the said table 1 through the medium of lower terminal screw-stems 19, removably fitted in the ears3 and maintained against accidental disconnection by nuts 20. The yoke 18 may be easily applied and disconnected, and it mayalso be secured to tightly clamp the oar-shank or be made loose enough to permit the shank of the oar to turn therein. The degree of binding of the yoke will be regulated by the choice of the oarsman, the'character of the oar, and the motion desired to be imparted to the latter. It will be noticed that the oar when applied in the improved lock will be prevented from becoming disengaged, and, moreover, the yoke can be placed directly over the portion of the car shank desired without requiring longitudinal movement of the oar to properly dispose the same.- 7

The improved lock is strong and durable, sensitive in its movements, and readily applicable to aboat, and though the preferred form of the same is shown it is obvious that changes in the form, size, proportions, and

minor details can be resorted to Without departing from the principle of the invention.

Having thus described the invention, what is claimed as new is 1. An oar-lock having an upper horizontally-rotatable table also capable of a swinging movement, and an arcuate yoke having lower terminal screw-stems removably applied to diametrically opposite portions of the said table.

2. An oar-lock having an upper horizontally-rotatable table also capable of a swinging movement, and an arcuate yoke having its terminals removably attached to said table.

3. An oar-lock having an upper horizontally-rotatable table provided with a central depending screw-threaded post, an arcuate yoke removably attached to said table, a lower table through which the said post ex- CLINTON A. TANSLEY.
